The doorbell rang, shattering the otherwise peaceful Saturday morning. Sarah scrambled to open the door, only to find her niece, Olivia, clutching a crayon-covered drawing in her tiny hand. "Look, Auntie Sarah!" Olivia declared, her face beaming. The drawing was an elaborate depiction of a castle, but what caught Sarah's attention was the tiny, winged figure perched atop one of the turrets. It was "Pip," her imaginary friend.

Sarah bent down, her heart thumping a little too fast, and ruffled Olivia’s hair. “Wow, that’s amazing, sweetie!” she exclaimed.

Immediately, she grabbed a thick black marker and started drawing a dragon swooping down to protect the castle. Olivia joined in and yelled, “He needs some armor!”
